Series V6 Flotect Mini-Size Flow Switch
Brand: Dwyer Instruments, LLC
The Series V6 Flotect® Flow Switch is surprisingly compact and specifically engineered to monitor liquid, gas, or air flows.
Time-tested in thousands of pipeline installations and processing plants around the world, this Series is Weatherproof, designed to meet NEMA 4, and Explosion-proof (listing included in specifications).
Tees are available for installation in pipelines from 1/2" to 2" (12.70 to 50.80 mm). With bushings added, the unit is easily adapted to 1/4" and 3/8" (6.35 and 9.53 mm) piping.
Features- A unique magnetically actuated switching design gives superior performance
- A free-swinging vane which attracts a magnet within the solid metal switch body, actuating a snap switch by means of a simple lever arm with no bellows, springs, or seals to fail
- Leak-proof body machined from bar stock
- Electrical assembly can be easily replaced without removing the unit from installation so that the process does not have to be shut down
- Choice of models in a tee with calibrated vane or field-adjustable trimmable vane
- Easy installation with simple pipe insert via tee and simple electrical switch connections
- High pressure rating of 1,000 psig (69 bar) with the brass body and 2,000 psig (138 bar) with the 316 SS body
- The low-flow model offers field-adjustable set point
